[Scikit-learn-general] [ANN] PyStruct 0.2

Hey everybody. I'm pleased to announce the release of PyStruct 0.2. After a bit of a pause in the project, the 0.2 release now packs some of the improvement contributed in the last 7 month. The highlights are: - The Block-Coordinate Frank-Wolfe algorithm, implemented in FrankWolfeSSVM (Thanks t

Re: [Scikit-learn-general] PCA vs Linear KPCA

Hi Shishir. The algorithms are identical. However the direction of the eigenvectors that generate the new coordinates are only defined up to the sign. So the sign of the axis in both PCA and KPCA is detemined by the details of the algorithm computing the eigenvector. I is not really surprising if

[Scikit-learn-general] PCA vs Linear KPCA

Hi Just wanted to know what is the difference between PCA and KPCA with linear kernel. They produce the same result on columns 1, 2, etc. But, the values in column 0 of the fitted transform of one is negative of other. Shouldn't they both be the same? -- sp
